我们外出学*重整预加氢热氢带油温度为260度。对吗?我认为要300度以上。还有热氢带油温度是根据什么定的?

我我这边一般控制在275左右 在压力一定的条件下 精致油杂质含量是控制预加氢温度的依据 杂质有:烯烃 卤数 金属

你这个热氢带油温度是不是指炉出口至反应器的温度吧
Reply #42017-01-11
260度足够,我们250度,只要保证油品在该压力下能完全汽化就可以

热情带油温度高,时间长了容易出现硫化态的催化剂被还原,一般热氢带油的温度定为200℃,时间不超过24小时,为宜。不同厂家的催化剂也是要求不一样的

带油温度260度足够了

热氢带油,是预加氢停止进料,用氢气退油吗?
Reply #82017-02-06
我厂预加氢热氢带油为180度,时间4小时即可。温度过高有催化剂还原的危险。

我们厂重整装置预加氢热氢带油温度一般是控加热炉出口温度280℃,太高的话对预加氢催化剂有影响,同时还要注意补氢量,控好高分罐压力(也相当于是保证系统循环氢量),防止催化剂结焦。带油原则是高分罐液位不再上涨,一般4个小时左右就差不多了。
